If you are talking about the Declaration of Independence of the United States, then, the social contract that the government gets its power from the people is mentioned in the following excerpt: <em>"That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government..."</em>
Enlightenment thinker Thomas Hobbes was one of the thinkers that talked about the social contract.
Other Enlightenment philosophers such as John Locke also wrote about popular sovereignty.
Baron of Montesquious and Jean-Jaques Rosseau were other thinkers that proposed interesting ideas about the form of governments and people's rights, that influenced further independence movements and revolutions.
